This handmade bracelet is a museum piece, Mavens! It is the most beautiful colors of the ocean. It is entrancing. I love the way it hugs the wrist. Oooh la la… I do not know what the materials are, for certain. It feels like it could be a light metal, a hard acrylic, or a thin leather. I honestly can’t tell! What I do know is that it is lightweight and comfortable to wear. The only real weight to it is the large, iridescent, beach blue glass stone. It is chunky and delicate all at the same time. It is a conversation and statement piece of jewelry. It is beguiling!
